We're going to need a whole lot more detail on the car.
Is it lowered? How low?
What camber specs at ride height?
Wheel specs-offset and spacers added?

That diameter tire is a bit taller and would be fine on the 2-LS but even on the 1-LS it shouldn't pose issues. For the back, the inner fender can be shaved to give clearance. If the wheels are very aggressive there are options like stretched tires and fender pulling. Don't know if I would go to that extent for G35 wheels unless there are some future wheels in mind that dictate an aggressive fitment.
